    Comprehensive geomorphological and sedimentological analyses confirmed three phases of Würm glaciation in the surroundings of Prášilské Lake and Stará Jímka, in the Bohemian Forest. Glaciations were affected by a steep east-facing slope, by plateaus on the adjacent ridges and by local geological conditions. A small valley glacier occurred during the first phase. In the second phase, a glacierrock glacier developed, probably based on remnants of the valley glacier. During the last phase glacial activity was divided into Stará Jímka and the stepped cirque of Prášilské Lake. A further shallow (3 m deep) lake in Stará Jímka was dammed by slope movements after deglaciation (14 cal. ka BP) and survived until 4 cal. ka BP. The presence of plateaus (deflation areas), across the approach of westerly winds was important for the development of glaciers in the Bohemian Forest. In the mid-mountains of central Europe, Pleistocene glaciation decreases significantly eastward, because of increasing continentality.
